Definitions

  • This invention pertains to a boost control device for internal combustion engines with an exhaust gas turbocharger comprising a bypass valve in a bypass line which is parallel to the exhaust gas turbine of the turbocharger, a motor operator for the bypass valve which can be loaded in the opening and closing directions and a control valve which feeds charge air to the motor operator as a function of temperature and, by means of another motor operator, as a function of boost pressure, in which the control valve feeds charge air to the motor operator of the bypass valve in the closing direction up to a pre-established boost pressure and wherein this feed can be vented into the environment by the control valve.
  • An object of the invention is to provide a device of the aforementioned type such that the boost control takes into account changes in the ambient effects and adjusts the charging air pressure and thus the maximum engine output to a uniform value so that the climate and altitude of the site of operation have no effect on the maximum output of the engine.
  • a boost control device of the aforementioned type with pressure control valve means which is loaded in the opening direction by the charge air, is loaded in the closing direction by means of a barometric plug, and which is exposed to the ambient pressure, and wherein means are provided for prestressing the barometric plug as a function of at least one of the ambient temperature and the charge air temperature.
  • the means for prestressing the barometric plug as a function of temperature includes an expanding element with a temperature-sensitive part that extends into a charge air line. Further, a wedge is provided in a plane extending transverse to the axis of the barometric plug, the wedge being displaced by the expanding element in opposition to the force of a compression spring.
  • the pressure control valve means controls a connecting line vented to the environment by a choke opening for the charge air to a motor operator of the control valve means and to the motor operator of the bypass valve in its opening direction. After the pressure control valve means opens, the control valve means blocks and vents to the environment exclusively the closing-direction feed of the charge air to the motor operator of the bypass valve.
  • the disclosed, preferred embodiment of the invention shown in the drawing features a boost control for internal combustion engines with an exhaust gas turbocharger.
  • a boost control for internal combustion engines with an exhaust gas turbocharger For the sake of simplicity, of the latter devices only a part of a bypass line which passes around the exhaust gas turbine and a part of a charge air line are depicted.
  • a boost control intervenes in a bypass line 1 of an exhaust gas turbine of an exhaust gas turbocharger, not shown, and controls charge air tapped from a charge air line 2 for the purpose of control.
  • bypass line 1 there is a bypass valve 3 with a motor operator 4 which can be loaded by the charge air in the opening and closing directions.
  • a compression spring 5 in motor operator 4 also acts in the closing direction; this compression spring prevents the bypass valve 3 from opening even when there is an underpressure in the charge air line 2.
  • the motor operator 4 is loaded via lines 6 and 7 which are connected to the charge air line 2; a control valve 8 and a pressure control valve 9 intervene in lines 6 and 7.
  • Pressure control valve 9 is flanged with its housing 10 directly to charge air line 2.
  • Housing 10 has a valve chamber 11 and a spring chamber 12.
  • Valve chamber 11 is connected to its environs by means of a throttle opening 13.
  • a valve bolt 17 of valve disk 16 extends through a seal 18 in a wall 19, which separates chambers 11 and 12, into spring chamber 12 which is connected to the ambient air via a hole 20.
  • a prestressed barometric plug 21 situated in spring chamber 12 acts on valve bolt 17 in the closing direction of pressure control valve 9.
  • the prestressing of barometric plug 21 can be varied by means of a wedge 22 located between the end of valve bolt 17 and barometric plug 21; this wedge can be moved by an expanding element 23 against a pull-back or compression spring 24 by way of increasing the prestressing.
  • the temperature-sensitive part 25 of expanding element 23 extends directly into charge air line 2.
  • Control valve 8 is attached with its housing 26 directly to pressure control valve 9.
  • the valve has a piston slide valve 28 with a ring-shaped control recess 29; the piston slide valve can be displaced against the force of a pull-back spring 27.
  • the end face 30 of piston slide valve 28 which faces away from pull-back spring 27 serves as a motor operator which can be loaded with charge air and forms the limit for a working chamber 32 adjacent to a stop 31 attached to the housing.
  • the working chamber 32 is connected on the one hand via a channel 33 to the valve chamber 11 of pressure control valve 9 and, on the other hand, is connected via a line 7 to the side of motor operator 4 of bypass valve 3 which can be loaded in the opening direction.
  • Another channel 34 leads from the charge air line into valve hole 14 of pressure control valve 9, and from there to a control opening 35 is housing 26 of control valve 8.
  • a second control opening 36 of control valve 8 is connected via a line 6 to the side of motor operator 4 of bypass valve 3 which works in the closing direction, and a third control opening 37 of control valve 8 opens into the ambient air.
  • control valve 8 In an end position of control valve 8 when its motor operator is not loaded with charge air, the first and second control openings 35 and 36 of control valve 8 are interconnected via control recess 29 of the piston slide valve 28 so that the charge air acts on bypass valve 3 in the closing direction and holds it closed.
  • pressure control valve 9 will open against the spring force of barometric plug 21. Then charge air will flow into valve chamber 11, from there into the working chamber 32 of control valve 8 and to the side of motor operator 4 of bypass valve 3 which works in the opening direction.
  • piston slide valve 28 of control valve 8 is displaced against the force of pull-back spring 27 so that the first control opening 35 is closed and via control recess 29 of piston slide valve 28 the second control opening 36 is connected to the third control opening 37.
  • the effect of this is that the side of motor operator 4 of bypass valve 3 which works in the closing direction is vented to the ambient air and only the side of the motor operator which works in the opening direction is loaded with the pressure of the charge air so that bypass valve 3 opens.
  • a drop in the ambient pressure and/or a rise in the charge air temperature lead to greater prestressing of barometric plug 21 and thus to a higher charging pressure.
  • changes in the environment and operation are compensated for and a maximum engine output which essentially remains constant at all times is achieved.
